Question:

I want to use a pair of Crossfire x1900 or variants with an Intel Conroe e6700 / e6800 CPU for folding, ultimately running 4x cores 2x CPU's and 2x GPU's with the soon to be released GPU core.

I also want the the boards to run on x16 < both of them >, not the master running x16 and slave at x8.

What combination of MB, RAM and Graphics card combination would do the job?
.
 
As I understand it it only supports one GPU atm.

As for rest P5B Deluxe tbh and the 16x and 8x stuff will NOT affect it, the B/W is only used up to about 2x, possibly 3x.

How you gonna get four cores??? :confused: Two machines?


How rich are you? Have your own Powerstation to run it!? :p

  1. You cant use 2*16 slots, only 8/8 if your on 975x or 16/4 if your on 965
  2. Wait for the client to come out before any decisions, we dont know much about support
  3. It depends if your overclocking, after features or what-have-you, a budjet would be nice too.
Also, concorde, 4x slot is around whats needed for a single card, i did some tests on my x1900 and the 4x slot results in a small but still there and noticable loss, 8x however was nothing.
 
As mentioned best to wait till the client is out. On monday i'll start a thread where those with X1900 cards can etst i and report their findings before peole go and shell out on expensive graphics cards. Its quite possible that it will allow you to run on two gpus initially, but we have to wait and see.

The other thing is, i don't think that folding is likely to hog much pic-e bandwidth as i should think it will mostly run from gpu ram. We also don't know if folding works much better with cards with more ram or if its better to get a faster card with less ram, just have to wait and see.

Ohh ... I didn't realise I could only run one ATI core ... was thinking I was able to run one core on each GPU :(

The other two cores would be one each on core processor.

As for the cost & power station ... that's what work is good for :D

Here's the best cruncher ever as far as I can tell: Mac Pro with dual 3.0 GHz Woodcrests (upgradable to dual 2.7 Ghz Kentsfields) with quad X1900XT cards.

That'd be 4 Conroe-esque cores on a 1333 MHz FSB along with four top-end GPUs all in on e stylish little aluminum box.

If only they'd come out with an Intel Mac client. Do you think Win NT could handle it? I suppose it's up to the drivers ATi provides.

You may be able to run it on multiple gpu cores like you can with cpu cores, and if you can't you will be able soon i think. Have to wait till monday to find out.
 
I looked at the Mac Pro, but didn't see a selection for Quad ATI's at least not yet.

Im assuming your referring to the R590 configuraitons that ATI are developing < 2x GPU's ber board>, then there's the slight issue of a F@H core to be released.

The Dual 3.0 Woodcrests look particularly interesting, especialy with the Conroe upgrade possibilities.


[EDIT]
As for the power requirments:

Power Station = Turbo-Cool 1KW - Power Plant
